I am well chuffed with the gusset since the designer had had some trouble getting it to do what she wanted and I was able to fix that. Now I'm having trouble at the top of the mitten though because it's not working for me as written. If I use a k2tog decrease as instructed I get a little line of dark yarn across the light but if I use k2togtbl my decrease points the wrong way. I'll have to tromp through my knitting books in search of a solution. (Suggestions are also very welcome!)
